REDHAT-BUG-1890653
First published: Thu Oct 22 2020(Updated: )
A divide-by-zero issue was found in QEMU in the dwc-hsotg (dwc2) USB host controller emulation. More specifically, HCCHAR_MPS was read from a device register and later used as divisor without performing any sanity check. This could allow a malicious/buggy guest to crash the QEMU process on the host, resulting in a denial of service.
